nghttp [OPTIONS]... <URI>...
HTTP/2 experimental client
.. describe:: <URI>
Specify URI to access.
.. option:: -v, --verbose
Print debug information such as reception and
transmission of frames and name/value pairs. Specifying
this option multiple times increases verbosity.
.. option:: -n, --null-out
Discard downloaded data.
.. option:: -O, --remote-name
Save download data in the current directory. The
filename is dereived from URI. If URI ends with '*/*',
'index.html' is used as a filename. Not implemented
yet.
.. option:: -t, --timeout=<SEC>
Timeout each request after <SEC> seconds.
.. option:: -w, --window-bits=<N>
Sets the stream level initial window size to 2\*\*<N>-1.
.. option:: -W, --connection-window-bits=<N>
Sets the connection level initial window size to
2\*\*<N>-1.
.. option:: -a, --get-assets
Download assets such as stylesheets, images and script
files linked from the downloaded resource. Only links
whose origins are the same with the linking resource
will be downloaded. nghttp prioritizes resources using
HTTP/2 dependency based priority. The priority order,
from highest to lowest, is html itself, css, javascript
and images.
.. option:: -s, --stat
Print statistics.
.. option:: -H, --header=<HEADER>
Add a header to the requests. Example: :option:`-H`\':method: PUT'
.. option:: --cert=<CERT>
Use the specified client certificate file. The file
must be in PEM format.
.. option:: --key=<KEY>
Use the client private key file. The file must be in
PEM format.
.. option:: -d, --data=<FILE>
Post FILE to server. If '-' is given, data will be read
from stdin.
.. option:: -m, --multiply=<N>
Request each URI <N> times. By default, same URI is not
requested twice. This option disables it too.
.. option:: -u, --upgrade

if the request URI has https scheme. If :option:`-d` is used, the
HTTP upgrade request is performed with OPTIONS method.
.. option:: -p, --weight=<WEIGHT>

[1, 256], inclusive.
Default: ``16``
.. option:: -M, --peer-max-concurrent-streams=<N>

remote endpoint as if it is received in SETTINGS frame.
The default is large enough as it is seen as unlimited.
.. option:: -c, --header-table-size=<SIZE>
Specify decoder header table size.
.. option:: -b, --padding=<N>

.. option:: --continuation
Send large header to test CONTINUATION.
.. option:: --no-content-length
Don't send content-length header field.
.. option:: --no-dep
Don't send dependency based priority hint to server.
.. option:: --dep-idle

.. option:: --version
Display version information and exit.
.. option:: -h, --help

The <SIZE> argument is an integer and an optional unit (e.g., 10K is 10 * 1024). Units are K, M and G (powers of 1024).
